IMPROVEMENT m STOVE-PLATFORMS.

Specification forming part of Letters Patent N 0. [86,475. dated January 23, 1877; application tiled December 21, 1876.

To all whom it may concern:

Be it known that I, CHARLES E. L. HOLMES, of city, county, and State of New. York, have invented a Stove-Platform, of which the follo wing is the specification V The object of my invention is a stove-platform, constructed as fully described hereafter, to secure the requisite stiffness and rigidity, and to insure a permanent and durable, highly-polished, and brilliant surface.

In the accompanying drawing, Figure l is a plan of my improved stove-platform Fig. 2, a transverse section and Fig. 3, an enlarged section of the compound material of which the platform is inade.

Ordinarystove-platforms are made of sheetzinc stamped or spun up to form a central flat bearing, a, and an inclined waved rim, 1). While zinc is well adapted for the manufacture of this class of articles, on account of its stiffness, durability, and cheapness, a finished article-cannot be made therefrom, owing to the readiness with which the surface can be acted upon by gases generated in the stove, which soon cause the formation of a white ox ide upon the surface, whilethe color of the zinc, even when polished, is dull and without luster.

Platforms made of brass, while capable of a fine polish, soon lose their luster, and are expensive, while tin, although capable of a forming a sheet, A, of compound metal, Fig. 3, consisting of a base or body, a, of zinc, and a face, I), of block-tin, or compound containing tin, or of a facing of block-tin united to a backing of sheet-iron, or its equivalent, so that the upper face is tin and the lower face is hard metal.

It is preferable to use zinc and tin in combination, as the two metals unite under pressure, are sufficiently malleable to be readily drawn or spun up to the required shape, and yet are stiff enough to support the weight .of a stove or other article. The platform thus produced, while possessing the rigidity of the zinc, capable of as ready manufacture, and costing but little more, has,in addition, all the advantages of an article made of block-tin,

possessing the brilliant durable color and lustrons surface, almost incapable of oxidation.
